If you haven't already done so, disable the option to break
large attachments into smaller chunks.
The most likely cause of this problem is email scanning by your
antivirus. Such scanning should be disabled. Also, McAfee and
Norton antivirus are not compatible with Windows Mail.
Those will need to be uninstalled and replaced with a more
compatible antivirus such as the free version of Avast.
Windows Mail does not have a size limit for sending messages,
but your ISP probably does. ISP-imposed size limits are usually
in the 2-20MB range.
